Essays on Electrical engineering

In isolation applications, such as situations where one needs to transmit signals despite the presence of high voltages, reject excessive noise, and eliminate ground loops, optocouplers and pulse transformers are commonly employed. Optocouplers use optical coupling while pulse transformers use magnetic coupling. However, designing pulse transformers is considerably more challenging compared to optocouplers. The load…

Secondarily, its thickness allows for wear over the life of the clutch. However, that wear results from a fundamental drawback of diabetics design. Since the armature is thick and massive, it has a high inertia, and all of its originally stationary mass must be “spun up” to match the rapidly rotating pulley and friction disk…

The duties of the section involve reagent storage and mixing, determining the dosage of reagents, ample preparation, metallurgical accounting and dispatch of the concentrate for further processing. Production – duties include receiving ore, ore milling, monitoring flotation cells, concentrate handling and tailings handling. The process at the concentrator is semi- automated and is monitored by…

An electric generator is fundamentally an electric motor working backwards. An electric motor converts electrical energy into mechanical energy. and an electric generator converts mechanical energy into electrical energy. An electric generator looks about indistinguishable to an electric motor. Each consists of a cringle that is able to revolve in a magnetic field. The electric…

In statistical signal processing, the sampling times are most often taken to be equally spaced. However, several applications need that non-uniform sampling is important. The major work on nonuniform sampling is for when the sampling times can be specified, and the signal processing community lacks tools to deal with standard issues like identification and decimation…

Abstract Electronic pills, smart capsules or miniaturized microsystems swallowed by human beings or animals for various biomedical and diagnostic applications are growing rapidly in the last years. This paper searched out the important existing electronic pills in the market and prototypes in research centers. Further objective of this research is to develop a technology platform…

Information technology and information system’s impact on many industries, one of the industries is IT appliances industry. We choose Samsung Electronics Co. as our topic in this industry. Samsung has been dedicated to create a better world for over 70 years through various businesses. Today, Samsung extent advanced technology, semiconductors, skyscraper and plant construction, petrochemicals,…

Introduction This lab was completed to investigate and map the magnetic field pattern of a single straight conductor by comparing it with the earth’s magnetic field. Quantitatively, the purpose of this lab was to determine the horizontal component of the earth’s magnetic field. Magnetic field and electric currents are naturally closely related because anytime a…

Introduction             Electroplating can be defined as the deposition of a metallic coating through the subjection of an object with a negative charge to a solution containing a salt containing positive metal ions. Under the influence of an electric charge, the positive ions are attracted to the negatively charged object where they are reduced hence…

There is a argument as to whether or non tablets are better than laptops. This is something that truly has interested me. In this essay we will compare the differences between three tablets and three laptops to see if we can find whether tablets are better than laptops or vise versa. Even though tablets are…
